Texas Instruments MSP430F5304IPT

Overview

MSP430F5304IPT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 8 KB flash, 6 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), a 10-bit 200 kSPS ADC with window comparator, one USCI (UART/IrDA/SPI/I²C), hardware multiplier, DMA, RTC module with alarm, and 31 GPIOs in a 48-pin LQFP package. It targets battery-powered sensor systems and digital timers requiring sub-2 µA standby current.

For engineers reviewing the MSP430F5304IPT datasheet, MSP430F5304IPT pinout, MSP430F5304IPT application, or MSP430F5304IPT equivalent, key selection criteria include its single-USCI configuration, 31 I/O count, LQFP-48 package footprint, 1.8–3.6 V operation, and <5 µs wake-up from LPM3 - critical for energy-constrained embedded control.

Technical Context

The MSP430F5304IPT implements a unified clock system (UCS) with FLL-based frequency stabilization, dual crystal support (XT1 for 32 kHz, XT2 up to 32 MHz), and internal sources (VLO, REFO). Its power management includes an integrated 3.3-V LDO with programmable core voltage regulation and supply supervision with brownout detection.

Peripherals are mapped via port mapping controller on Port 4, enabling flexible USCI_B1 and USCI_A1 signal routing. Unlike higher-family variants, it integrates only one USCI module (not two), and omits Comparator_B - confirmed by device comparison table and functional block diagram specific to PT/RGZ packages.

FAQ

What is the maximum operating frequency of the MSP430F5304IPT?

The MSP430F5304IPT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This allows real-time execution of time-critical tasks such as 200 kSPS ADC sampling or high-resolution PWM generation while maintaining ultra-low power consumption in active mode.

Does the MSP430F5304IPT include a hardware real-time clock (RTC)?

Yes, the MSP430F5304IPT integrates a dedicated RTC_A module with alarm capabilities, calendar function, and calibration registers. It operates in LPM3 with crystal (32 kHz XT1) or internal VLO, consuming only 1.9 µA at 2.2 V - enabling precise timekeeping for scheduling, timestamping, and low-power wake-up events in the MSP430F5304IPT.

How many USCI modules does the MSP430F5304IPT support?

The MSP430F5304IPT supports exactly one USCI module, configurable as either USCI_A0 (UART/IrDA/SPI) or USCI_B0 (SPI/I²C) - not both simultaneously. This is confirmed in the device description and Table 3-1, distinguishing it from MSP430F5308IPT and MSP430F5310IPT which include two USCI modules.

What is the ADC resolution and channel count on the MSP430F5304IPT?

The MSP430F5304IPT features a 10-bit successive-approximation ADC (ADC10_A) with 200 kSPS throughput, 6 external analog input channels (A0–A5), and 2 internal channels (VeREF+, VeREF−). It includes a programmable window comparator for autonomous threshold detection without CPU intervention - a key capability in the MSP430F5304IPT for sensor monitoring.

Is the MSP430F5304IPT pin-compatible with other devices in the MSP430F53xx family?

The MSP430F5304IPT shares the same 48-pin LQFP (PT) package footprint and pinout with MSP430F5308IPT and MSP430F5309IPT, but differs in peripheral allocation: it lacks USCI_B0 and Comparator_B signals present on those variants. Pin compatibility is mechanical and electrical for shared signals, but firmware and schematic must account for missing peripherals in the MSP430F5304IPT.
